A mystery shopper is not a professional spy. Mystery shoppers are the secret eyes of service companies that need reliable judgment of their market competitiveness. However, earning an income as a mystery shopper is a legal job to assess the qualities of the service of a company, and help it grow and succeed. In other words, mystery shopping is about making truthful value judgment of the friendliness of the shopping environment, the helpfulness of the frontline stuff, the abilities of the shopping assistants, etc. You should be able not only to observe all these and make logical conclusions about your overall customer satisfaction, but also to remember details and watch out for particular signs. In the end, you will be asked to write down your impressions, either on paper or on line.
To be a successful mystery shopper, you need to meet some requirements. First you should feed the company that hires you with correct and reliable information about your shopping experience. Besides, you also need basic writing skills. You should write in a simple and understandable way, but still show both your overall impressions and the details you are asked about.
Don’t worry if you are a new mystery shopper—the company that hires you should provide you with instructions how to complete your shopping tasks. If the company does not provide you with prior(预先) training, you should doubt that it might be a mystery shopping test which you should be careful with. Therefore, you should always get instructions about the mystery shopping rules that you have to follow; about the things you should watch out for; about the way to fill in and present your response, etc.  Becoming an experienced mystery shopper pays well. As you’re likely to get more invitations, earn greater income, and be contracted by more mystery shopping companies.
